Habitchulator
A person who waits like they're waiting for a pizza that never arrives, and gets really pissy about it.
I've been habitchulating since the meeting started. I'm ready to throw my coffee at the boss.
He's been habitchulating for 45 minutes. Now he's texting his mom about it.
I'm habitchulating in the hallway. My neighbor just walked by and said, 'You look like you're about to explode.'
